Home -> Community -> Mailing Lists -> Oracle-L -> RE: internal date value
Thomas:
I'm a SAS guy who must pull Oracle data from the back-end DB.
SAS stores dates internally as elapsed days since Jan 1, 1960. If I request an Oracle date field, SAS creates a datetime variable, number of seconds since midnight Jan 1, 1960. Rather than use SAS functions to extract the date ( e.g. datepart function ), I'd like to push that back to Oracle if possible and create a simple date field on SAS. I can accomplish the desired effect with:
select date_fld - to_date('01Jan1960','ddmonyyyy') as sas_date
but I was hoping there was an Oracle function to surface the internal value ( appears to be days since Jan 1, 1968 ). Presumably such a function would be more efficient.
Thanks for your help.

Harry,
Can you explain why you need to raw internal value? Just curious.

You gather it wrong :)
Oracle stores date in 8 bytes, one for each: year, month, day, hour,
min, ... etc.

Folks:
>From what I gather, Oracle stores dates as the number of elapsed days
since
Jan 1, 1968. When I query a column of type 'DATE', it returns me the
default format, dd-mon-yy. I know I can use
to_char(date_col,'YYYYMMDD')
etc... to define many output formats.
What can I do to get the raw internal value of the date? i.e. today is 13172.
Thanks.
